Privacy policy
Short version: your upload is deleted as soon as it's split, the stems are deleted after 24 hours, our own code sets no cookies, and the ads use cookies (with your consent where the law requires it).
Audio you upload
- Your file is used only to make your stems. The original upload is deleted as soon as the split finishes (or fails).
- The stems are stored for 24 hours so you can download them, then deleted automatically.
- Anyone with the link to your split can open it during those 24 hours, so share the link only with people you want to have the stems.
- We don't use your audio to train models, and we don't listen to it.
Information we keep
- Daily limits: to enforce the free daily limit, we keep a scrambled (salted, one-way hashed) version of your IP address that changes every day. We can't turn it back into your IP. Counters are deleted after two days.
- Job records: the file name, length, detected tempo and status of each split, deleted along with the stems after 24 hours.
- In your browser: the site remembers your recent splits in your browser's local storage so you can find them again. That never leaves your device.
Services we use
- Cloudflare hosts the website and passes requests to our processing servers. It may also show a "verify you are human" check (Turnstile) to stop bots.
- Modal runs the GPU servers that split the audio and stores the files for 24 hours.
- Google AdSense shows ads and manages cookie consent (see below).
- Cloudflare Web Analytics counts visits (pages viewed, country, browser type, which site sent you) so we can see how the site is used. It doesn't use cookies or track you across other websites.

Ads
This site is paid for by ads served by Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this and/or other sites on the internet.
You can opt out of personalized advertising by visiting Google's Ads Settings, and learn more at How Google uses information from sites or apps that use its services. You can also opt out of some third-party vendors' use of cookies for personalized advertising at aboutads.info.
If you're in the European Economic Area, the UK or Switzerland, you'll be asked for consent before cookies are used for ads. If you're in a U.S. state with privacy laws (such as California), you can opt out of the "sale" or "sharing" of your personal information for targeted advertising using the Privacy choices link. We don't sell your information in any other way.
Children
This site isn't directed at children under 13, and we don't knowingly collect information from them.
Your rights
Depending on where you live, you may have the right to ask what information we hold about you, to have it deleted, or to object to how it's used. Because we keep almost nothing about you (no accounts, no names, and uploads and stems are deleted within 24 hours), there is usually nothing to hand over, but you can always write to us.
